Function project_curve2_certified

pub fn project_curve2_certified(
    curve: &BSplineCurve<DVec2>,
    target: DVec2,
    options: CertifiedProjectionOptions,
) -> Result<CurveProjectionCertificate2, GeomError>

Globally bound the closest point on a clamped planar B-spline curve.

Positive rational weights make every refined segment lie in the convex hull of its Euclidean control points. Interval-aware homogeneous knot insertion and outward-rounded subdivision tighten those hulls until the global distance gap meets the requested tolerance.
